error when exec'ing scp from python

Question

this code is giving following error:

os.system("scp %s:/export/home/sample/backup.sql  %s:/home/rushi/abc.sql" % (a, b))

Permission denied (publickey,keyboard-interactive).
lost connection

a and b are the command line arguments which accept user name and machine name as arguments:

eg: [email protected] .

Answer 1

This has nothing to do with Python and everything to do with SSH.

Permission denied (publickey,keyboard-interactive).

It's telling you you have failed to log in. I suggest you either sort your key-based auth out or pass it a password.

See: http://unixhelp.ed.ac.uk/CGI/man-cgi?ssh+1

Or instead of trying to use the scp command, use a pure-python method.
